2Hybrid Connectivity Design
- 2.1Choosing Direct Connect vs VPN
Connect on-prem to AWS—understand Direct Connect (dedicated), Site-to-Site VPN, and the virtual private gateway (VGW), and how to choose. Learn the trade-offs of stability, cost, and setup speed.
- 2.2Direct Connect Architecture and Resiliency
Go deeper on DX—private/public/transit VIFs, BGP, redundancy via multiple connections/locations, and the DX Gateway. A single connection is a single point of failure.
- 2.3Scaling Hybrid with Transit Gateway
Bundle at a hub—understand the Transit Gateway, segmentation via TGW route tables, DX/VPN attachments, and when to use it vs peering. Centrally bundle many VPCs and on-prem.
